JACOB A. FAY, OF BALTIMORE, MARYLAND.

HORSE-POWER.

i Specification of Letters Patent No. 978, dated October 10, 1838.

ery; and I do hereby declare that the follo-wing is a full and eXact description thereof.

In the accompanying drawing 7c, is, represents the upper face of -a flat wheel, upon which the horse, or other'animal is to walk. f

This `wheel may be placed horizontally, or it may be somewhat inclined tothe horizon, so as to cause the weight of the animal upon it to tend to give it motion. 0, o', 0, are the arms of this wheel. Iron straps, or braces, m, m, are employed to brace or support these arms, y, being a standard, or vertical block, rising from the center of the wheel, for these iron braces to rest upon. A verti-4 cal block, or standard, s, s, is placed below the center `of the wheel, being either fixed in the ground, or rising from the frameof the machine, as the case may be. A pointed, or other formed` center pin u, rests on a step prepared to receive it, on the upper end of the block, s, s', thus sustaining the wheel at its center.

. The horse is to be placed on that part of theV wheel marked 7c', c, where the lower side of the wheel rests upon a friction roller; or trundle a, the gudgeons of which run in the upright d of the frame ci, CZ, and in the port 7L.; upon the aXis of this trundle is the whirl, or band wheel t, b, from which the power is to be conveyed to whatever is to be driven by the power of the animal, which is to be attached to the ports e, e, to keep him in his position, two friction wheels c, upon posts fw, are placed under the wheel la, lc, at equal distance from the trundle a, to sustain the wheel, and prevent its tipping, but they must not standso high as to interfere with the bearing of the wheel upon the trundle or friction roller.

d, (Ltd, is the frame of the machine, which may be put together in any convenient manner, as may be preferred.

By the particular `manner in which I have combined together the respective parts of my horse power the weight and draft of the animal is to give motion to machinery by the friction of the tread wheel upon a roller, or trundle as above described, without the use of cogs, or any similar gearing. I do not however claim the driving by means of friction, without the employment of cogs, this c having been previously effected, but

What I do claim is- The manner in which I have constructed and combined together the respective parts of my apparatus as above described; that is to say, I claim the manner of balancing the wheel upon which the horse is to walk, on its center, without a vertical shaft, in combination with the mode ofbracing the same, Y

and of sustaining the part on which the animal is to walk.
